Why Choose the Lovato BFK15000A110 Power Factor Correction Contactor?
The Lovato BFK15000A110 is a three-pole power factor correction contactor designed specifically for switching capacitor banks in industrial power factor correction systems. Part of the Lovato BFK150 series, it incorporates limiting resistors for capacitor switching and provides an IEC AC-6b operational power rating of 100 kvar at 400 V.
Designed for high-capacity capacitor switching duties, the BFK15000A110 combines a 165 A conventional free-air thermal current with a 690 V rated insulation voltage and 8 kV rated impulse withstand voltage. Its dedicated BFK construction makes it suitable for automatic power factor correction equipment where reliable control of capacitor stages is required.
This specific variant uses a 110 V AC 50/60 Hz control coil. Its AC-6b operational power ratings include 50 kvar at 230 V, 100 kvar at 400 V, 115 kvar at 440–480 V and 150 kvar at 690 V, while screw or 35 mm DIN rail fixing provides flexible installation within industrial electrical panels.

High-Capacity Capacitor Switching for Power Factor Correction
Power factor correction systems use capacitor banks to compensate for reactive power within electrical installations. Switching high-capacity capacitor stages requires contactors specifically designed for AC-6b duty and capable of handling the electrical conditions associated with capacitor energisation.
The Lovato BFK15000A110 is engineered for this application and includes limiting resistors for capacitor switching. Its 100 kvar rating at 400 V, 165 A thermal current rating and 110 V AC 50/60 Hz control coil make it a purpose-built switching component for appropriately rated industrial power factor correction systems.
Typical Applications
- Automatic power factor correction panels.
- High-capacity industrial capacitor bank switching.
- Reactive power compensation systems.
- Industrial electrical distribution panels.
- Power factor correction equipment and control cabinets.
- Capacitor switching stages rated up to 100 kvar at 400 V.
